The objectives of this program were to research and develop a fully enclosed Information Technology (IT) rack system for 100 kilowatts (KW) of IT load that provides its own internal power and cooling with High Voltage Alternating Current (HVAC defined as 480 volt) and chilled water as the primary inputs into the system and accepts alternative energy power sources such as wind and solar. For maximum efficiency, internal power to the IT equipment uses distributed High Voltage Direct Current power (HVDC defined as 360-380 volt) from the power source to the IT loads. The management scheme aggressively controls energy use to insure the best utilization of available power and cooling resources. The solution incorporates internal active management controls that not only optimizes the system environment for the given dynamic IT loads and changing system conditions, but also interfaces with data center Building Management Systems (BMS) to provide a complete end-to-end view of power and cooling chain. This technology achieves the goal of a Power Usage Effectiveness (PUE) of 1.25, resulting in a 38% reduction in the total amount of energy needed to support a 100KW IT load compared to current data center designs.

This report discusses the background of cluster munitions in the U.S. military, and the current Department of Defense (DOD) and Obama Administration stances on the topic. It also discusses the two major international initiatives to address cluster munitions: the Convention on Cluster Munitions (CCM) and negotiations under the U.N. Convention on Prohibitions or Restrictions on the Use of Certain Conventional Weapons (CCW).

Tank Farm and Closure Engineering is evaluating changes to the Actinide Removal Process facility operations to decrease the MST concentration from 0.4 g/L to 0.2 g/L and the contact time from 12 hours to between 6 and 8 hours. For this evaluation, SRNL reviewed previous datasets investigating the performance of MST at 0.2 g/L in salt solutions ranging from 4.5 to 7.5 M in sodium concentration. In general, reducing the MST concentration from 0.4 to 0.2 g/L and increasing the ionic strength from 4.5 to 7.5 M in sodium concentration will decrease the measured decontamination factors for plutonium, neptunium, uranium and strontium. The decontamination factors as well as single standard deviation values for each sorbate are reported. These values are applicable within the sorbate and sodium concentrations used in the experimental measurements. Decreasing the MST concentration in the ARP from 0.4 g/L to 0.2 g/L will produce an increase in the filter flux, and could lead to longer operating times between filter cleaning. The increase in flux is a function of a number of operating parameters, and is difficult to quantify. However, it is estimated that the reduction in MST could result in a reduction of filtration time of up …

As part of the Saltstone formulation work requested by Waste Solidification Engineering (WSE), Savannah River National Laboratory (SRNL) was tasked with preparing Saltstone samples for fresh property analysis and hydraulic conductivity measurements using actual Tank 50 salt solution rather than simulated salt solution. Samples of low level waste salt solution collected from Tank 50H during the first, second, and third quarters of 2011 were used to formulate the Saltstone samples. The salt solution was mixed with premix (45 wt % slag, 45 wt % fly ash, and 10 wt % cement), in a ratio consistent with facility operating conditions during the quarter of interest. The fresh properties (gel, set, bleed) of each mix were evaluated and compared to the recommended acceptance criteria for the Saltstone Production Facility. ASTM D5084-03, Method C was used to measure the hydraulic conductivity of the Saltstone samples. The hydraulic conductivity of Saltstone samples prepared from 1Q11 and 2Q11 samples of Tank 50H is 4.2E-9 cm/sec and 2.6E-9 cm/sec, respectively. Two additional 2Q11 and one 3Q11 sample were not successfully tested due to the inability to achieve stable readings during saturation and testing. The hydraulic conductivity of the samples made from Tank 50H salt solution compare …

In this project, we have successfully developed a full scale commercially ready carbon molecular sieve (CMS) based membrane for applications in H{sub 2} recovery from refinery waste and other aggressive gas streams. Field tests at a refinery pilot plant and a coal gasification facility have successfully demonstrated its ability to recovery hydrogen from hydrotreating and raw syngas respectively. High purity H{sub 2} and excellent stability of the membrane permeance and selectivity were obtained in testing conducted over >500 hours at each site. The results from these field tests as well as laboratory testing conclude that the membranes can be operated at high pressures (up to 1,000 psig) and temperatures (up to 300 C) in presence of aggressive contaminants, such as sulfur and nitrogen containing species (H{sub 2}S, CO{sub 2}, NH{sub 3}, etc), condensable hydrocarbons, tar-like species, heavy metals, etc. with no observable effect on membrane performance. By comparison, similar operating conditions and/or environments would rapidly destroy competing membranes, such as polymeric, palladium, zeolitic, etc. Significant cost savings can be achieved through recovering H{sub 2} from refinery waste gas using this newly developed CMS membrane. Annual savings of $2 to 4MM/year (per 20,000 scfd of waste gas) can be realized by …

A letter report issued by the Government Accountability Office with an abstract that begins "Generally consistent with the views of key stakeholders we interviewed, state and school district officials cited 17 federal requirements as most burdensome for them. These requirements were related to the Elementary and Secondary Education Act (ESEA) Title I, Part A; the Individuals with Disabilities Education Act (IDEA) Part B; national school meals programs; or other requirements related to the receipt of federal funds. Officials described the burdens associated with these requirements as complicated, time-intensive, and duplicative, among other things, and characterized most of the requirements as being burdensome in multiple ways. For example, several officials told us that collecting data for IDEA reporting requirements—such as the number of data elements collected—takes a significant amount of time and resources. State and district officials also noted benefits of some requirements, for example, that the process to create individualized education programs can help protect the rights of students with disabilities."

A letter report issued by the Government Accountability Office with an abstract that begins "In Georgia, quality and sustainability issues jeopardize the long-term usefulness of the Samtskhe-Javakheti road project. The Millennium Challenge Corporation (MCC) funded the rehabilitation of about 217 kilometers of road linking the previously isolated Samtskhe-Javakheti region with Tbilisi, the country’s capital, and reducing the driving time from 8 ¼ hours to 2 ¾ hours. The project was intended to increase exports from the region, integrate people in the region with the rest of Georgia, and expand trade with Turkey and Armenia. However, the urgency to meet fixed time frames resulted in problems implementing the project’s quality assurance framework. For example, the construction supervisor did not have enough staff to properly monitor construction and ensure quality. Despite several recommendations from MCC’s independent engineer, MCC and its Georgian counterpart, the Millennium Challenge Account (MCA-Georgia), did not adequately increase the number of construction supervisors, which resulted in pavement defects in parts of 5 of the 11 road sections and deterioration of structures such as drainage and retaining walls. One 15-kilometer section contained enough defects that the road had to be completely repaved. Furthermore, much of the repair work was to …

This report provides background information and potential issues for Congress on the Navy's irregular warfare (IW) and counterterrorism (CT) operations. News reports about the May 1, 2011, U.S. military operation in Pakistan that killed Osama Bin Laden state that the operation was carried out by a team of 20 to 25 Navy special operations forces, known as SEALs, specifically an elite unit known as Seal Team 6.

Correspondence issued by the Government Accountability Office with an abstract that begins "A federal dig once policy would likely have several advantages, including potentially decreasing the frequency of construction on major highways and the cost of installation, while accelerating access to and reliability of broadband networks. However, disadvantages—which could be exacerbated by a requirement to install conduit as part of certain federally funded highway construction—include the potential to install conduit that telecommunications companies might not use and to divert highway funding away from highway construction. U.S. Department of Transportation (DOT), Federal Communications Commission (FCC), and state DOT officials we spoke with supported the concept of a dig once policy, but suggested alternative approaches to a federal requirement to install conduit in all covered projects. For example, FCC officials expressed support for a federal requirement for evaluation of the feasibility and need for conduit during federal highway construction, and state and U.S. DOT officials expressed support for a federal role in facilitating discussion and best practice sharing among states implementing broadband deployment policies."
